Routing two different networks over one interface using an HWIC on a 2811

hello below is my configuration for my router. I have enabled ip routing as well and rebooted my router.

Here is what I can do.

1) I can ping the 10.0.33.x network from the 192.168.123.x network

2) I can get out to the internet using 192.168.123.x network VIA fa 0/2/0

What  I CAN NOT do

1) get out to the internet from 10.0.33.x network. using GW 192.168.123.253?

2) also is it possible to somehow keep this config and route my 10.0.33.x network out int fa 0/0.34 if I put it on a sub interface?

Routing two different networks over one interface using an HWIC

do you have a route back to 10.0.33.0/24 from your gateway/firewall?

make sure you have a route in your gateway which will point to the 10.0.33.0/24 network, something like this;

ip route 10.0.33.0 255.255.255.0 192.168.123.1

Yes I do believe I have a route back

when I enter the static route

ip route 10.0.33.0 255.255.255.0 192.168.123.1

%Invalid next hop address (it's this router)

should I try my gateway .253 which is my firewall? instead of .1

shouldent OSPF handle this since I have both networks enabled on OSPF?

Are you talking about putting the ip route statement

ip route 10.0.33.0 255.255.255.0 192.168.123.1

in the firewall?

yes, the firewall needs to have a route back to the 10.0.33.0/24 network
